Monitor dims when reactivated

by danawenco / March 5, 2009 2:32 AM PST

Hi, my monitor has been dimming/turning pinkish when I reactivate it (moving my mouse for example) after the screen saver turns on, but it would return to normal after 10 - 15 seconds.

If I set the timer of the screen saver to 1 minute, I don't see the problem, but if I set the timer to be 10 minutes, I see the problem.

Is it likely to be my monitor or video card?

I have a 2 year old Toshiba laptop, using Vista. Thanks a lot.

That's a well known issue.

The cause is technical and is known to happen in the later years of CCFL lights.


Just enjoy your monitor and give it a few seconds for the molecules to do their thing.

Hi Bob,

Thanks for the link. So it looks like my monitor is reaching its "half-life". Does it help to set the timer of my screen saver to be more frequent? The monitor of my previous laptop died after 2 years as well so it must be me.

Thank you.

I don't think it matters.

The pink, red shift until the CCFL warms up is well known. It's actually easy to fix if you can get the parts and have a laptop that lets you change them but the repair has far too much risk to fix an issue that clears up in less than a minute.

I have this 10 year old Palm PDA that is worse yet I still use it and will never fix that even though I could. It's a fine thing to have around to demonstrate the issue.

Your choice on the settings but all one can do is to always power down CCFL tubes from DAY ONE. Once it pink or red shifts you can't undo it.

Thanks again for your help Bob!

Next time I buy a laptop I will remember that.

When my current one does die I will probably follow the instructions on your link and try to replace the LCD as a learning exercise Happy

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
